Received Smith's letter of 13 April. Thanks for the mistletoe berries. A severe drought in Scotland has killed many young trees, herbaceous plants and crops "so that famine is staring us in the face". Working on his index and has now reached 'Didynamia' and 1500 species and has completed his commentary on the first part of the "Herbarium Amboinense" intended for the Wernerian Society in Edinburgh but despairs at their tardiness. Will continue his work on the "Hortus Malabaricus".
